Dynamic digital communication system control
First Claim
1. A method of controlling a digital communication system having a plurality of communication channels on which transmissions of signals are communicated by the signals being transmitted and received, the signals being affected by crosstalk interference during transmission, each of the communication channels being used by users and each user having at least one transmitter and at least one receiver, the method comprising the steps of:
- collecting information about the channel, signal and far-end crosstalk interference characteristics of the communication channels;
in response to the collecting, creating a model of the channel, signal and far-end crosstalk interference characteristics of the communication channels; and
synchronizing the transmitted and received signals across multiple transmitters and receivers to permit signal processing using the model to remove far-end crosstalk interference from the signals.

Abstract
Control of a digital communication system having a plurality of communication lines on which signals are transmitted and received is implemented using a variety of methods and systems. According to one embodiment of the present invention, a method is implemented where the signals are affected by interference during transmission and each of the communication lines has at least one transmitter and at least one receiver. A model is created of the interference characteristics due to the signals carried on the communication lines. Interference characteristics for a line are determined based on the model and actual signals carried on other communication lines different from the line for which the characteristics are being determined. Actual interference is compensated for on the communication line using the determined interference characteristics.
